Can JavaScript frameworks like React or Vue also be optimized?

Yes, Single Page Applications (SPAs) based on React, Vue, Svelte or Angular have specific performance challenges: large initial JavaScript bundles, slow client-side rendering and lack of search engine indexability. We optimize SPAs through Server-Side Rendering (SSR) or Static Site Generation (SSG), route-level code splitting, tree shaking to eliminate unused code, lazy loading of components and optimized hydration strategies. For existing SPAs without SSR, we also evaluate migration to frameworks like Next.js, Nuxt.js or SvelteKit.
